How the colour ages
Plant dyes settle over the first 3–4 washes, a little excess colour may rinse out. After that the tone stays put and slowly softens into a gentle patina. Sunlight fades it fastest, so dry in the shade.
The 01 running sock is a naturally dyed organic cotton sock built for a full day on your feet: a 200-needle knit with a terry-cushioned footbed, a ribbed crew cuff that stays up, and a hand-linked toe so there is no ridge under the toes.
Designed in Amsterdam and knitted in a family-run mill in northern Portugal, it is coloured with madder root, weld and earth pigments instead of azo dyes. Breathable enough for a summer run, quick-drying enough to be a winter sock, and simple to care for — wash cool, dry flat, and it keeps its shape for years.

Where and how it's made
Fibre — Aegean region, Türkiye
GOTS certified organic cotton, grown without synthetic pesticides and rain-fed where the season allows.
Knitting — Northern Portugal
Knitted on circular sock machines in a family-run mill near Barcelos, with a hand-linked toe seam so there is no ridge under the foot.
Dye — plant and mineral baths
Dyed in low-temperature baths using madder root, weld and iron mordants instead of azo dyes. Water is filtered and re-used within the dye house.
Finishing
Washed, paired and packed by hand in unbleached paper — no plastic polybags.
Care instructions
- Machine wash cold (30°C) on a gentle cycle, inside out.
- Wash with similar colours — naturally dyed yarns settle over the first few washes.
- Do not bleach, do not tumble dry.
- Line dry flat, away from direct sunlight.
- No ironing needed; the ribbing recovers as it dries.
